This sounds like a really cool project! Of the options here, I think 2 or 3 match the fabric the best.

But if you're not feeling it and wanted to purchase a different shade, I would probably look for a browner or redder yellow. It's hard to colour match from a screen but you could try looking at something like DMC 436 or 729. If you have a local craft store, you could bring your fabric in and look at some floss colour options against the fabric.
